SRAS840 MNG Application Field and Working Principle

SRAS840 MNG is an advanced rectifier diode with moderately high current capability and low weight. This diode is widely used in a variety of applications in the fields of automotive rectifier applications, home appliances, telecommunications systems, power supplies, and rectifier systems. It also serves as a functional foundation of advanced healthcare products. SRAS840 MNG is a single rectifier that has a high-performance structure and is capable of optimal reliability and thermal resistance.Structure and Characteristics
SRAS840 MNG has a press-fit mounting construction and includes a mesh-grid structure consisting of a leadframe and resin monolith. This construction is composed of an anode, a cathode and a hermetically sealed mold compound. It has a higher reverse voltage capability than previous versions and exhibits excellent surge current characteristics. This device also has an adequate range of current when compared with other diodes in its class. Additionally, it has a high breakdown voltage commensurate with its current capability, low forward voltage drop, and a low thermal resistance.Applications
SRAS840 MNG is suitable for various rectifier systems and applications. It is especially well-suited for automotive rectifier systems, power supplies, and other general rectifier applications, where high reliability and high thermal withstand capability are critical. It is also suitable for power converters, power factor correction circuits, DC-DC converters, and boost converters.Working Principle
SRAS840 MNG is an ideal device for rectification, voltage regulation, and protection. An applied voltage across its anode and cathode terminals causes an electron current to flow. This current is limited in its magnitude by the forward resistance of the device. Additionally, when the current reaches a certain value, an avalanche breakdown is experienced and the current no longer increases. The current required to initiate an avalanche breakdown is also known as the critical breakdown voltage.Conclusion
SRAS840 MNG is an advanced rectifier diode that is widely used in a variety of applications in the fields of automotive rectifier applications, home appliances, telecommunications systems, power supplies, and rectifier systems. Its press-fit mounting construction and mesh-grid structure give it high reliability and thermal withstand capability, making it a great asset for rectifier systems. It also has a high breakdown voltage commensurate with its current capability, low forward voltage drop, and low thermal resistance, making it a reliable option for power converters, power factor correction circuits, DC-DC converters, and boost converters.
